Metro B Line (Minnesota)

The Metro B Line is an under construction bus rapid transit route in Minneapolis and St. Paul. The route will operate mostly on Lake Street in Minneapolis before crossing the Mississippi River into St. Paul and operating mostly on Selby Avenue and ending in downtown St. Paul. The route was identified in Metro Transit's 2014 Arterial Transitway Corridors Study as one of eleven local routes to be upgraded to bus rapid transit. The route will have "train-like" features to speed up service, such as signal priority, all-door boarding, further stop spacing, and specialized vehicles. Planning and design was completed in 2021, with construction beginning in May 2023. The line will join a number of Metro Transit's future Metro system lines, as well as the currently operating A Line, C Line, and D Line. Full funding for the line was secured in October 2020 with a final $35 million from the state of Minnesota.

Construction on the line began in 2023 on the eastern portion of the line. The 2024 construction season is expected to focus on the western portion of the line with an opening in June 2025.
